計(jì)及梯級(jí)水電站群的水火電節(jié)能調(diào)度策略
[Abstract]:Considering the three factors of generating unit output, energy consumption cost and pollution discharge, and the coupling parameters of cascade power station and hydraulic power station, as well as the comprehensive benefit of hydro-thermal motor group, the minimum abandoned water quantity of cascade hydropower station is established. The multi-objective comprehensive energy-saving dispatching model with the lowest cost of thermal power consumption and the minimum pollution emission is proposed, and the scheduling strategy of hydropower energy-saving generation with cascade hydropower stations is put forward. By using scale conversion method, the multi-objective comprehensive energy saving dispatching model of cascade hydropower stations, which has the lowest energy consumption cost of thermal power units and the lowest pollution emission, is transformed into a single objective function with different weight coefficients. The hybrid penalty function optimization algorithm is used to transform the problem into an unconstrained optimization problem and the Hessian matrix is used to improve the optimization algorithm to overcome the problem of the selection of reduced coefficients. Through the simulation of the hydro-thermal power system with four cascade hydropower stations and three thermal power plants, the optimization results show that the algorithm is feasible and has obvious energy-saving effect.
